A dynamical approach to the spatiotemporal aspects of the Portevin-Le Chatelier effect: Chaos,turbulence and band propagation
G. Ananthakrishna, M. S. Bharathi
Experimental time series obtained from single and poly-crystals subjected to a constant strain rate tests report an intriguing dynamical crossover from a low dimensional chaotic st…
Dynamics of Crossover from a Chaotic to a Power Law State in Jerky Flow
M. S. Bharathi, G. Ananthakrishna
We study the dynamics of an intriguing crossover from a chaotic to a power law state as a function of strain rate within the context of a recently introduced model which reproduces…
Chaotic and power law states in the Portevin-Le Chatelier effect
M. S. Bharathi, G. Ananthakrishna
Recent studies on the Portevin - Le Chatelier effect report an intriguing crossover phenomenon from a low dimensional chaotic to an infinite dimensional scale invariant power law r…
Multifractal burst in the spatio-temporal dynamics of jerky flow
M. S. Bharathi, M. Lebyodkin, G. Ananthakrishna +2
The collective behavior of dislocations in jerky flow is studied in Al-Mg polycrystalline samples subjected to constant strain rate tests. Complementary dynamical, statistical and…
